剩余图未与主图对齐 [英] Residual plot not aligned with main graph

问题描述

导致我的主图未对齐的残差图出了什么问题?我的代码在下面.

What is wrong with my residual plot that is causing to not be aligned with my main graph? My code is below.

import matplotlib.pyplot as plt
from scipy import stats
import numpy as np

x = np.array([0.030956,0.032956,0.034956,0.036956,0.038956,0.040956])
y = np.array([10.57821088,11.90701212,12.55570876,13.97542486,16.05403248,16.36634177])
yerr = [0.101614114,0.363255259,0.057234211,0.09289917,0.093288198,0.420165796]
xerr = [0.00021]*len(x)
fig1 = plt.figure(1)
frame1=fig1.add_axes((.1,.3,.8,.6))
m, b = np.polyfit(x, y, 1)
print 'gradient',m,'intercept',b
plt.plot(x, m*x + b, '-', color='grey', alpha=0.5) 
plt.plot(x,y,'.',color='black',markersize=6)
plt.errorbar(x,y,xerr=0,yerr=yerr,linestyle="None",color='black')
plt.ylabel('$1/\sqrt{F}$ $(N)$',fontsize=20)
plt.autoscale(enable=True, axis=u'both', tight=True)
plt.grid(False)
frame2=fig1.add_axes((.1,.1,.8,.2))
s = m*x+b #(np.sqrt(4*np.pi*8.85E-12)/2.23E-8)*x
difference = y-s
plt.plot(x, difference, 'ro')
frame2.set_ylabel('$Residual$',fontsize=20)
plt.xlabel('$2s+d_0$ $(m)$',fontsize=20)

推荐答案

，您可以指定轴限制.问题是自动缩放会以不同的方式移动您的两个图.如果您插入两行代码，每行代码指定一个轴限制，它将对其进行修复.

you can specify the axis limits. the problem is that autoscale is moving your two plots differently. if you insert 2 lines of code, each specifying the axis limits, it will fix it.

plt.axis([.030,.0415, 10, 17])  #line 17
plt.axis([.030,.0415, -.6, .8]) #line 26

我相信这就是您想要的.

i believe this is what you're looking for.
